Abstract

A knitting machine needle having at least at one point S2, S3, S4 or S5 of its hook, a cross-section that is asymmetrical with respect to a longitudinal center plane M. Preferably, this cross-section is an oval cross-section and, more preferably, an elliptical cross-section. Using this measure, the robbing-back effect can be affected in a targeted manner during the knitting operation.
